170 페이지 - Astronomical Observations made at the Observatory of Cambridge by the Rev. JAMES CHALLIS, MA, FRS, FRAS, Plumian Professor of Astronomy and Experimental Philosophy in the University of Cambridge, and Fellow of Trinity College.
61 페이지 - ... the terms which involve lower powers of a certain quantity m, which denotes the ratio of the sun's mean motion to that of the moon, than the fourth ; a demonstration of this most important proposition has been given by Sir John Lubbock in the Philosophical Magazine for the present year.
76 페이지 - Power 160; the field of view 19' in diameter, and angular subtense" (or apparent extent), " 53^, is perfectly full of brilliant stars, unusually equal in magnitude and distribution over the whole area. Nothing but a sight of the object itself can convey an adequate idea of its exquisite beauty.
157 페이지 - Newtonian telescope of five inches aperture, of my own manufacture, and though the mirrors have since been much tarnished, and the instrument otherwise injured, its performance is incomparably superior to what it was in America. Venus sometimes shines with a light so dazzling, that at a distance of thirteen feet from the window I have distinguished the hands of a watch and even the letters of a book. Some few months since, having met with the statement that the satellites of Jupiter had been seen...
93 페이지 - ... He is distinguished in England as the discoverer of a large number of planets, particulars of which discoveries he invariably sends to the " Times" newspaper, in letters dated from Mr. Bishop's Observatory, Regent's Park. The Council of the Astronomical Society awarded him, in 1852, their gold medal "for his astronomical discoveries, and in particular for the discovery of eight small planets ;" previous to which, in 1848, they had voted him their testimonial for his discovery of Iris and Flora.
235 페이지 - ... I can affirm that I gathered it from Kepler's theorem about twenty years ago. And so Sir Christopher Wren's examining the ellipsis over against the focus shews, that he knew it many years ago, before he left off his enquiry after the figure by an impressed motion and a descent compounded together. There was another thing in Mr. Hooke's letters, which he will think I had from him. He told me, that my proposed experiment about the descent of falling bodies was not the only way to prove the motion...
175 페이지 - A preliminary Treatise on the law of Repulsion, as a universal law of nature: in which the Mosaic history of creation is vindicated and sustained, and various natural phenomena (heretofore mysterious) clearly explained. Philadelphia, 1853. 8vo. TREGO, CHARLES B. A Geography of Pennsylvania, with a separate description of each county, and questions for teachers. To which is appended a travellers
222 페이지 - ... the lower end of the first axis is a weight which more than counterpoises the upper part. If then there be no rotation in the bar about the first axis, the effect of the weight is to produce a rotation about the second alone, bringing down the first axis into a vertical position. If now the first axis be held horizontally or obliquely, and a rotatory motion be given to the bar about it, on letting the axis go, we compound both rotations; and the resulting effect is, that the weight will no longer...
159 페이지 - Hence the loss of light in passing from the zenith through a homogeneous atmosphere of 5.2 miles will be .303. I was much astonished at first discovering that the air had so great absorbent powers, and many ideas are suggested by the fact.
25 페이지 - Finally, of the 125 comets whose elements are given in the collection of Schumacher and Olbers, up to 1823, the number of retrograde comets under 10° of inclination is only two out of nine, and under 20°, seven out of twenty.three. A plane of motion therefore, nearly coincident with the ecliptic, and a periodical return, are circumstances eminently favourable to direct revolution in the cometary as they are decisive among the planetary orbits.
